Not sure how Odin Sphere is forgotten given the announcement of the remake, and that it's Vanillaware's most popular game. Lots of people are reminded of it when Vanillaware announces a new title.
Eternal Sonata is alright but looked amazing back in the day (not sure how it holds up today). There was this one dungeon that looked like a pain in the ass, but fortunately, I cleared it on my first time solving it.
